IMLEROVEMENT IN SPINDLE FOR SHUTTLES.

The Schedule referred to in these Letters Patent and making part of the same.

To all whom it may comer/n:

Be it known that I, CHARLES E. SMITH, of Lowell,` in the county of Middlesex, and State of Massachusetts, have invented certain new and useful Improvements in the Spindles of Loom-Shuttles, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, making part of this specication, in which- Figure l represents the top side of one of my improved shuttle-spindles;

' Figure 2, a side elevation, with a section of a cop of filling, B, as applied to the spindle for weaving Figure 3, a central longitudinal section on the line Figures 4 and 5 are modifications of my invention;

Figure 6 represents the top side of ran ordinary shuttle-spindle; and I Figure 7 a horizontal plane Section of iig. 6, with a cop shown in section. j

This invention relates to that kind of shuttle-spindies which have long been known as split spindles, and which are employed where the filling used for weaving isspun on mules, and not on throstle-fr'ames, and on cops, and not on bobbins, and has for its object to retain the cop on the spindle, and prevent the Same being upset or separated by the sudden blows' ofthe shuttle which carries the spindle and the [cop of lling.

The ordinary split spindles which are used in shuttles, and which carry cop-lilling, are made in two parts, a, a, and either welded'or brazed together at their ends, and finished smoothly, and gradually tapered Hom the end to the shoulder b. The parts or sides a a are sprung apart about one-eighth of an inch, so that when the cop of lling is pushed on to such Smooth-tapered,

spindle, the parts or sides are pressed together, thereby producing friction, for the purpose of holding .the cop on the ordinary spindle.

This limited friction between the interior of the cop of filling, (which has a hole through it, formed by the mule-spindle on which it was' spun,) and the exterior of the smooth-tapered spindle, is inadequate for the certain retention of the cop'on the spindle, and by the Sudden and violent blows of Ithe shuttle against the pickers at the ends of the lay, the cop of filling is frequently upset or separated, when only a small portion of the iilling has run ofi', which necessitates the removal of the separated cop of filling, which is thrown out as Waste.

To obviate theabove-nauied di'lculty, and prevent the frequent waste of valuable material, I take the same kind of spindle, and before springing the Sidesm apart, and while the said spindle is being finished, and form therein several annular notches or serrations and shoulders, c, as shown in figs. 1,12, and 3, by removing a portion of the substance of the spindle, and tapering the same from the highest pait of one shoulder to the next beyond, as also clearly shown.

I then spread or spring the sides a apart, and the spindle is ready to be c pplied to the shuttle, and to receive the cop of iilling for the weaving-operation, which cop is pushed on to the spindle in the usual way, passving easily over the shoulders c, which prevent' the cop being too easily removed.

Then the cop of filling is thus applied to this improved spindle in a shuttle, and the shuttle put in operation in the loom, I have found it impossible to upset or separate or derange the vfilling toretard its proper action, and all the filling will run ot', leaving the spindle bare, and the cop-tube gfree for removal. The shoulders c hold the hlling, and prevent the separation of the cop.

Instead lof annular serrations and Shoulders, I sometimes form simply transverse notches, e, in the sides a, as shown in fig/l, and I have found these notches to answer nearly or quite as well for holding the cop of `filling as the annular shoulders c, which I consider equivalents of each other.

. Instead ofthe shoulders c, or the notches e, I Sometimes form annular corrugations or swells on the spin'- dle, with intervening hollows between them, as shown in iig. 5. Y

These swells and hollows serve very well for holding the cop of filling on the spindle, but I prefer the shoulders or the notches, `a's before described.

What I claim as of my invention, and desire to secure by Letters Patent, is-

lA split shuttle-spindle, notched or serrated on both sides, or on` its entire circumference, Substantially as and for the purposes set forth.
